This application is based upon and claims priority to Chinese Patent Application No. 201610617941.9, filed on Jul. 29, 2016, the entire content of which is incorporated herein by reference.

TECHNICAL FIELD

The present disclosure generally relates to the technical field of network security, and more particularly, to a method and apparatus for Bluetooth (BT)-based identity recognition.

BACKGROUND

During BT communications between terminals, it is necessary to determine user identities of the opposite ends to determine whether a communication process is secure.

In a related conventional technology, a first terminal establishes a BT connection with a second terminal. The first terminal sends user identity recognition information to the second terminal, and the second terminal identifies whether a user identity of the first terminal is legal according to the recognition information. If the user identity of the first terminal is legal, the second terminal communicates with the first terminal through the BT connection.

A Wireless Fidelity (WiFi)-based identity recognition method is also provided in the related conventional technology. A server determines a relationship between a terminal and a smart device, and establishes a first mapping table including a mapping relationship between a user account of the terminal and an identifier (ID). The terminal establishes a WiFi connection with the smart device. The smart device acquires a user account of the terminal, and sends the user account to the server. The server searches the first mapping table for an ID corresponding to the user account, and sends the found ID to the smart device. The smart device determines the ID as a user identity corresponding to the terminal.

In such an implementation, however, the smart device is required to remain a network connection with the server during identity recognition of the terminal. When the smart device may not remain the network connection with the server, identity recognition of the terminal may not be executed. As a result, communication between the smart device and the terminal may be insecure. In addition, more time is consumed when the smart device determines the ID of the terminal through the server, which may cause a lower identity recognition efficiency.

The method and apparatus of the present disclosure are directed towards overcoming one or more the problems set forth above.

DETAILED DESCRIPTION

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise represented. The implementations set forth in the following description of exemplary embodiments do not represent all implementations consistent with the present disclosure. Instead, they are merely exemplary apparatuses and methods consistent with some aspects related to the present disclosure as recited in the appended claims.

FIG. 1 is a schematic diagram illustrating an implementation environment 100 for exemplary embodiments of the present disclosure. The implementation environment 100 may include a terminal 110, a BT-enabled smart device 120, and a server 130. The terminal 110 establishes a communication connection with the server 130 through a communication network 140. The communication network 140 may be a wired network or a wireless network. The terminal 110 establishes a communication connection 150 with the smart device 120 through a BT connection.

The terminal 110 may be any electronic equipment capable of establishing a BT connection, such as a mobile phone, a tablet computer, a portable laptop computer or a desktop computer.

The server 130 may be a computer server, a server cluster including a plurality of computer servers, or a cloud computing serving center.

In the exemplary embodiment, the server 130 determines a relationship between the terminal 110 and the smart device 120, generates a first mapping table including a mapping relationship between a user account of the terminal 110 and an ID, and sends the mapping relationship to the smart device 120. Then, the terminal 110 establishes the BT connection 150 with the smart device 120. The smart device 120 acquires the user account of the terminal 110, and searches the first mapping table for the ID corresponding to the user account, and determines the ID as a user identity corresponding to the terminal 110.

In the exemplary embodiment, the server 130 sends to the smart device 120 in advance the mapping relationship between the user account of the terminal 110 and the ID, such that the smart device 120 may perform identity recognition on the terminal 110 even when it does not remain the network connection 140 with the server 130. In addition, less time is consumed by a process that the smart device 120 locally determines the ID of the terminal 110, such that identity recognition efficiency can be improved.

FIG. 2 is a flow chart of a method 200 for BT-based identity recognition, according to an exemplary embodiment. The method 200 may be applied to the implementation environment 100 in FIG. 1, and may include the following steps.

In step 201, a BT connection is established with a first terminal.

In step 202, a first user account of the first terminal is acquired through the BT connection.

In step 203, a first preset mapping table is searched for a first ID corresponding to the first user account. The first preset mapping table includes a mapping relationship between at least one user account and at least one ID. Each ID corresponds to a respective user account, and the mapping relationship is determined and sent to a smart device by a server.

In step 204, a user identity corresponding to the first terminal is determined according to the first ID.

In the method 200, the first user account of the first terminal is acquired through the BT connection established with the first terminal, and the first preset mapping table is searched for the first ID corresponding to the first user account. The first mapping table includes the mapping relationship between the at least one user account and the ID corresponding to each user account. The mapping relationship is determined and sent to the smart device by the server. The user identity corresponding to the first terminal is determined according to the first ID. In this way, the smart device communicates with the terminal after recognizing the user identity of the terminal, such that the problem of communication insecurity caused by communications between an illegal terminal and the smart device is solved, and the effect of ensuring communication security is achieved.

FIG. 3 is a flow chart of a method 300 for BT-based identity recognition, according to another exemplary embodiment. In the exemplary embodiment in FIG. 3, a binding relationship between a second terminal 320 and a smart device 330 is to be established. The method 300 may include the following steps.

In step 301, a BT connection is established between the second terminal 320 and the smart device 330.

A BT protocol is a wireless technology standard capable of implementing communications between terminals. A connection established between the second terminal and the smart device by virtue of the BT protocol is referred to as a BT connection.

The step 301 includes that: the second terminal actively establishes the connection with the smart device, or the smart device actively establishes the BT connection with the second terminal.

In the exemplary embodiment, since the second terminal is required to establish a binding relationship with the smart device, the second terminal is also required to acquire a device ID of the smart device, that is, step 302 is executed.

In step 302, the smart device 330 sends a device ID of the smart device 330 to the second terminal 320 through the BT connection.

The device ID of the smart device is configured to uniquely identify the smart device. In this exemplary embodiment, after the second terminal establishes the BT connection with the smart device, the smart device may actively send its own device ID to the second terminal. Alternatively, the second terminal may send an ID acquisition request to the smart device, and the smart device sends its own device ID to the second terminal according to the ID acquisition request. There are no limits made to a manner for triggering sending of the device ID in the embodiment.

During practical implementation, after the second terminal establishes the BT connection with the smart device, the second terminal may display device IDs of all smart devices connected with the terminal in a display interface of a preset client, and display binding controls in areas corresponding to the device IDs of unbound smart devices. When the second terminal receives a triggering operation by a user over a binding control, the second terminal executes step 303.

In step 303, the second terminal 320 acquires the device ID of the smart device 330 through the BT connection.

In step 304, the second terminal 320 sends the device ID, a second user account of the second terminal and a first terminal ID to a server 340. The first terminal ID is a terminal ID of the second terminal 320.

The second user account of the second terminal may be an operating system account for login of the user in the second terminal, an application account for login of the user in an application of the second terminal, an account stored in the second terminal, an ID of the second terminal, and the like. The second user account is not limited in the embodiment.

The first terminal ID is configured to uniquely identify a terminal, which may be a media access control (MAC) address and the like. There are no limits in the embodiment.

The second terminal sends the second user account, the acquired device ID of the smart device and the first terminal ID to the server. The server is a server corresponding to the user account. For example, when the user account is a Xiaomi account, the server is a Xiaomi server. Therefore, when receiving the second user account, the server may recognize the second user account and establish a relationship between other information and the second user account.

In some embodiments, the second terminal may also generate a binding request, and adds the device ID, the second user account and the first terminal ID into the binding request for sending to the server.

In step 305, the server 340 receives the device ID of the smart device 330, the second user account and the first terminal ID from the second terminal 320 which establishes the BT connection with the smart device 330.

In step 306, the server 340 establishes a binding relationship among the device ID, the second user account and the first terminal ID, and generates a binder ID according to the binding relationship.

The binder ID is an ID corresponding to the second terminal which establishes the binding relationship with the smart device.

The server establishes the binding relationship among the device ID, the second user account and the first terminal ID. Namely, the server binds the smart device identified by the device ID and the second terminal corresponding to the second user account.

Then, the server is also required to generate an ID according to the relationship between the second terminal and the smart device. Since the relationship between the second terminal and the smart device is the binding relationship in the embodiment, the second terminal is also required to generate the binder ID, and determines the binder ID as the ID corresponding to the second terminal. The server stores the device ID, the second user account, the first terminal ID and the binder ID.

In the illustrated embodiment, the ID may be a character string with a preset bit number, for example, the character string of the binder ID may be 11 or 00 when the preset bit number is 2. There are no limits made in the embodiment.

In step 307, the server 340 generates a mapping relationship between at least one user account and each ID.

After generating the ID of the second terminal, the server is also required to notify the smart device of the ID. At this moment, the server generates the mapping relationship between the ID and the second user account, and sends the mapping relationship to the smart device.

In step 308, the server 340 sends the second user account and the binder ID to the smart device 330.

After the second terminal establishes the binding relationship with the smart device, the ID of the second terminal is the binder ID, and the server sends the second user account and the binder ID to the smart device.

In step 309, the smart device 330 receives the second user account and the binder ID from the server 340, and adds the second user account and the binder ID into a first mapping table as a set of mapping relationship.

The smart device adds the second user account and the binder ID which are sent by the server into the first mapping table as a set of mapping relationship.

In the illustrated embodiment, a process of establishing the binding relationship between the second terminal 320 and the smart device 330 is illustrated in step 301 to step 309. An identity recognition process between the second terminal 320 and the smart device 330 is described below. In the process of recognizing an identity of the second terminal 320, the second terminal 320 is the first terminal in the exemplary embodiment in FIG. 2 and the second user account is the first user account in the exemplary embodiment in FIG. 2. Step 310 is executed when the BT connection is established between the second terminal 320 and the smart device 330. When the BT connection is not established between the second terminal 320 and the smart device 330, it is necessary to establish the BT connection between the second terminal 320 and the smart device 330 before step 310.

In step 310, the second terminal 320 sends the second user account of the second terminal 320 to the smart device 330 through the BT connection.

In this exemplary embodiment, after the second terminal establishes the connection with the smart device, the second terminal sends its own second user account to the smart device.

In step 311, the smart device 330 acquires the second user account of the second terminal 320 through the BT connection.

In step 312: the smart device 330 searches the first preset mapping table for a first ID corresponding to the second user account. The first mapping table includes a mapping relationship between at least one user account and at least one ID. Each ID corresponds to a respective user account.

The first mapping table stores the mapping relationship between the at least one user account and the ID corresponding to each user account. The smart device searches the first mapping table for a user account which is the same as the second user account according to the acquired second user account. The first ID corresponding to the user account that is the same as the second user account in the mapping table is the first ID corresponding to the second user account.

In this exemplary embodiment, since the second terminal establishes the binding relationship with the smart device, the first ID found by the smart device is the binder ID.

In step 313, the smart device 330 determines the first ID as a user identity corresponding to the second terminal 320.

Since the first ID found by the smart device is the binder ID, the user identity is a binder.

In this exemplary embodiment, the smart device provides different access rights for terminals corresponding to different user identities. At this moment, step 314 is executed. That is, the first mapping table includes the mapping relationship between the at least one user account and the ID corresponding to each user account, and may include IDs of at least two different levels. The IDs of different levels correspond to different access right information. The ID levels have a positive correlation relationship with levels of the access rights indicated by the access right information.

In the illustrated embodiment, the ID levels may be related to security of the user identities, that is, a level of an ID is higher if security of a user identity is higher, and the level of the ID is lower if the security of the user identity is lower. The levels of the access rights may be related to the number of functions provided by the smart device, that is, the number of functions provided by the smart device is larger if a level of an access right is higher, and the number of the functions provided by the smart device is smaller if the level of the access right is lower. In such a manner, the smart device provides more functions for a terminal corresponding to a secure user identity, and provides fewer functions for a terminal corresponding to an insecure user identity. As a result, communication security is further ensured.

In step 314, the smart device 330 further searches a second mapping table for first right information corresponding to the first ID. The second mapping table includes a mapping relationship between at least one ID and at least one piece of right information. Each piece of right information corresponds to a respective ID.

The second mapping table includes the mapping relationship between the at least one ID and the right information corresponding to each ID. The right information is configured to indicate an access right over the smart device.

For example, when the first ID is a binder, the corresponding first right information corresponds to all functions provided by the smart device.

In step 315, the smart device 330 communicates with the second terminal 320 according to the first right information through the BT connection.

When the first right information, found from the second mapping table by the smart device and corresponding to the binder ID, corresponds to all the functions provided by the smart device, the second terminal determines that all the functions of the smart device may be called.

For example, the second terminal may be a mobile phone of a user, and the smart device may be a printer in a house of the user. The mobile phone displays the printer connected with the mobile phone on an interface, and displays a “bind” button for binding with the printer after the mobile phone establishes a BT connection with the printer. When the user clicks the “bind” button, the mobile phone acquires a printer ID from the printer, and the printer sends the printer ID to the mobile phone. The mobile phone sends its own user account, a mobile phone ID and the printer ID to a server. The server establishes a binding relationship among the user account, the mobile phone ID and the printer ID, and generates a binder ID corresponding to the mobile phone which establishes the binding relationship with the printer. The server generates a mapping relationship between the binder ID and the user account, and sends the mapping relationship to the printer. The printer adds the user account of the mobile phone and the binder ID into a first preset mapping table. At this point, the mobile phone establishes the binding relationship with the printer.

In a using process, after the mobile phone establishes the BT connection with the printer, the mobile phone sends its own user account to the printer. The printer searches the first preset mapping table for a user account that is the same as the received user account. An ID corresponding to the found user account is the binder ID, and the printer confirms that a user identity of the mobile phone is a binder.

In the method 300 provided by the present disclosure, the second user account of the second terminal is acquired through the BT connection established with the second terminal The first preset mapping table is searched for the first ID corresponding to the second user account. The first preset mapping table includes the mapping relationship between the at least one user account and the ID corresponding to each user account, and the mapping relationship is determined and sent to the smart device by the server. The user identity corresponding to the second terminal is determined according to the first ID. In this way, the smart device communicates with the second terminal after recognizing the user identity of the second terminal, such that the problem of communication insecurity caused by communications between an illegal terminal and the smart device is solved, and the effect of ensuring communication security is achieved.

In addition, the IDs may be divided into the binder IDs or the sharer IDs, such that the user identity of the terminal is expanded.

The IDs of different levels correspond to different right information, and the levels of the IDs have a positive correlation relationship with the levels of the access rights indicated by the right information. As a result, different access rights are provided for terminals corresponding to different user identities. High-level access rights are set for high-level IDs, and low-level access rights are set for low-level IDs. That is, more functions are provided for a terminal corresponding to a secure user identity, and fewer functions are provided for a terminal corresponding to an insecure user identity. Therefore, communication security is further ensured.

In some embodiments, after the second terminal establishes the binding relationship with the smart device, the second terminal may further share the smart device to a third terminal for the third terminal to establish a sharing relationship with the smart device.

FIG. 4 is a flow chart of a method 400 for BT-based identity recognition, according to yet another exemplary embodiment. In the exemplary embodiment in FIG. 4, a sharing relationship between a third terminal 420 and the smart device 330 is to be established. The method 400 may include the following steps.

In step 401, the second terminal 320 acquires a third user account of the third terminal 420 and the device ID of the smart device 330.

In this exemplary embodiment, the second terminal is a terminal which establishes a binding relationship with the smart device, and the third terminal is a terminal which confirms to participate in sharing after the second terminal shares the smart device to each additional terminal. For example, after the terminal 320 is bound with the smart device 330, the terminal 320 may share the smart device 330 to the terminal 420. The terminal 420 can confirm to participate in sharing.

The third user account of the third terminal may be an operating system account for login of a user in the third terminal, an application account for login of the user in an application of the third terminal, an account stored in the third terminal, an ID of the third terminal, and the like. The third user account is not limited in the embodiment.

During practical implementation, after the second terminal establishes the binding relationship with the smart device, the second terminal displays an interface of sharing the smart device in a display interface of a preset client. When the second terminal receives the third user account, input in an input box of the interface by the user, of the third terminal and a triggering operation of the user over a share control, the second terminal reads the device ID, acquired in a binding relationship establishment process, of the smart device, and then executes step 402.

In step 402, the second terminal 320 sends the third user account of the third terminal 420 and the device ID to the server 340.

The second terminal sends the third user account of the third terminal and the acquired device ID of the smart device to the server. Herein the server is a server corresponding to the third user account. For example, when the third user account is a Xiaomi account, the server is a Xiaomi server. Therefore, when receiving the third user account, the server may recognize the third user account and establish a relationship between other information and the third user account.

In some embodiments, the second terminal may also generate a sharing request, and adds the device ID and the third user account into the sharing request for sending to the server.

In step 403, the server 340 receives the third user account of the third terminal 420 and the device ID of the smart device 330 from the second terminal 320.

In step 404, the server 340 sends query information to the third terminal 420 according to the third user account.

The query information is configured to query about whether the third terminal confirms to participate in sharing. Herein the query information at least includes the device ID of the smart device and a second terminal ID, the second terminal ID being a terminal ID of the third terminal.

In step 405, the third terminal 420 receives the query information sent by the server 340.

In step 406, when determining to participate in the sharing according to the query information, the third terminal 420 sends the third user account and the second terminal ID of the third terminal 420 to the server 340.

The third terminal displays the received query information, and also displays an “OK” control and a “cancel” control. When receiving a triggering operation of the user over the “OK” control, the third terminal determines to participate in the sharing, and sends the third user account and the second terminal ID of the third terminal to the server. When receiving a triggering operation of the user over the “cancel” control, the third terminal determines not to participate in the sharing, and the flow chart ends.

In step 407, the server 340 receives the third user account and the second terminal ID of the third terminal which are sent by the third terminal 420 after determining to participate in the sharing according to the query information.

In step 408, the server 340 establishes a sharing relationship among the device ID, the third user account and the second terminal ID, and generates a sharer ID according to the sharing relationship.

The sharer ID refers to an ID corresponding to the third terminal which establishes the sharing relationship with the smart device.

The server establishes the sharing relationship among the device ID, the third user account and the second terminal ID.

Then, the server is also required to generate an ID according to the relationship between the third terminal and the smart device. Since the relationship between the third terminal and the smart device is the sharing relationship in the embodiment, the server is also required to generate the sharer ID, and determines the sharer ID as the ID corresponding to the third terminal. The server stores the device ID, the second user account, the second terminal ID and the sharer ID.

In step 409, the server 340 generates a mapping relationship between at least one user account and at least one ID. Each ID corresponds to a respective user account. In the embodiment, the ID is the sharer ID.

In step 410, the server 340 sends the third user account and the sharer ID to the smart device 330.

After generating the ID of the third terminal, the server is also required to notify the smart device of the ID. At this moment, the server generates the mapping relationship between the ID and the third user account, and sends the mapping relationship to the smart device.

In step 411, the smart device 330 receives the third user account and the sharer ID from the server 340, and adds the third user account and the sharer ID into the first preset mapping table as a set of mapping relationship.

The first preset mapping table includes the mapping relationship between the at least one user account and the ID corresponding to each user account. The smart device adds the third user account and the sharer ID which are sent by the server into the first preset mapping table.

Herein, a process of establishing the sharing relationship between the third terminal and the smart device is illustrated in step 401 to step 411. An identity recognition process between the third terminal and the smart device is described below. In the process of recognizing an identity of the third terminal, the third terminal corresponds to the first terminal in the embodiment in FIG. 2 and the third user account corresponds to the first user account in the embodiment in FIG. 2.

In step 412, the third terminal 420 establishes a BT connection with the smart device 330.

In step 413, the third terminal 420 sends the third user account of the third terminal to the smart device 330 through the BT connection.

In the embodiment, after the third terminal establishes the BT connection with the smart device, the third terminal sends its own third user account to the smart device.

In step 414: the smart device acquires the third user account through the BT connection.

In step 415, the smart device searches the first preset mapping table for a first ID corresponding to the third user account. The first mapping table includes the mapping relationship between the at least one user account and the at least one ID Each ID corresponds to a respective user account.

In the embodiment, since the third terminal establishes the sharing relationship with the smart device, the first ID found by the smart device is the sharer ID.

In step 416, the smart device 330 determines the first ID as a user identity corresponding to the third terminal 420. Since the found first ID of the third terminal is the sharer ID, the user identity is a sharer.

In this exemplary embodiment, the smart device provides different access rights for terminals corresponding to different user identities. At this moment, step 417 is executed. That is, the first preset mapping table includes the mapping relationship between the at least one user account and the ID corresponding to each user account, and includes IDs of at least two different levels. The IDs of different levels correspond to different right information, and the levels of the IDs have a positive correlation relationship with levels of the access rights indicated by the right information.

Herein, the levels of the IDs are related to security of the user identities. That is, a level of an ID is higher if security of a user identity is higher, and the level of the ID is lower if the security of the user identity is lower. The levels of the access rights are related to the number of functions provided by the smart device. That is, the number of functions provided by the smart device is larger if a level of an access right is higher, and the number of the functions provided by the smart device is smaller if the level of the access right is lower. In such a manner, the smart device provides more functions for a terminal corresponding to a secure user identity, and provides fewer functions for a terminal corresponding to an insecure user identity. As a result, communication security is further ensured.

In step 417, the smart device 330 searches a second mapping table for first right information corresponding to the first ID. The second mapping table includes a mapping relationship between at least one ID and at least one piece of right information. Each piece of right information corresponds to a respective ID.

The second mapping table includes the mapping relationship between the at least one ID and the right information corresponding to each ID. The right information is configured to indicate an access right over the smart device.

For example, when the first ID is a sharer, the corresponding first right information corresponds to part of functions provided by the smart device.

In step 418, the smart device 330 communicates with the third terminal 420 according to the first right information through the BT connection.

When the first right information, obtained from the second mapping table by the smart device and corresponding to the sharer ID, corresponds to part of the functions provided by the smart device, the third terminal determines that part of the functions of the smart device may be called.

For example, the third terminal may be a mobile phone of a family member in a family, and the smart device may be a printer. A mobile phone 1 of a family member 1 establishes a binding relationship with the printer. When the member 1 shares the printer to another family member 2, the member 1 inputs a user account of the member 2 in the mobile phone 1, and sends the user account of the member 2 and a printer ID to the server. The server receives the user account of the member 2 and the printer ID, and sends query information to the mobile phone 2 of the member 2 according to the user account of the member 2. The member 2 sends the user account of the member 2, a mobile phone ID of the mobile phone 2, and the printer ID to the server through the mobile phone 2 when confirming to participate in sharing. The server establishes a sharing relationship among the user account of the member 2, the mobile phone ID of the mobile phone 2 and the printer ID, and generates a sharer ID corresponding to the mobile phone 2. The server generates mapping between the sharer ID and the user account, and sends the mapping to the printer. The printer adds the user account of the member 2 and the sharer ID into a first mapping table. At this point, the mobile phone 2 participating in the sharing establishes the sharing relationship with the printer.

In a using process, after the mobile phone 2 establishes a BT connection with the printer, the mobile phone 2 sends its own user account to the printer. The printer searches the first preset mapping table for a user account that is the same as the received user account. An ID corresponding to the identified user account is the sharer ID. The printer confirms that a user identity of the mobile phone 2 is a sharer.

In some embodiments, when there exists no ID corresponding to the user account of the terminal in the first mapping table, the smart device determines that the user identity of the terminal is a stranger, and an access right corresponding to the ID of the stranger is of the lowest level.

In the methods 200, 300, and 400 provided by the present disclosure, the first user account of the first terminal is acquired through the BT connection established with the first terminal, and the first preset mapping table is searched for the first ID corresponding to the first user account. The first mapping table includes the mapping relationship between the at least one user account and the ID corresponding to each user account. The mapping relationship is determined and sent to the smart device by the server. The user identity corresponding to the first terminal is determined according to the first ID. In this way, the smart device communicates with the terminal after recognizing the user identity of the terminal. As a result, the problem of communication insecurity caused by communication between an illegal terminal and the smart device is solved, and the effect of ensuring communication security is achieved.

The IDs are divided into binder IDs and/or sharer IDs, such that the user identity of the terminal is expanded.

The IDs of different levels correspond to different right information, and the levels of the IDs have the positive correlation relationship with the levels of the access rights indicated by the right information. Thus, different access rights are provided for terminals corresponding to different user identities, for example, high-level access rights are set for high-level IDs, and low-level access rights are set for low-level IDs. Namely, more functions are provided for a terminal corresponding to a secure user identity, and fewer functions are provided for a terminal corresponding to an insecure user identity. Therefore, communication security is further ensured.
